i have heard that the Poly motors shared the same block architecture with the early Hemi's and that the Hemi heads would bolt onto the poly block. is this true???

No, the 277,301 and & 318 will not accept a HEMI head though other engines can. In example the old Firedome engines will take a HEMI head easy. It is much like the "LA" and "Magnum" series engines that need abit of everything from the block up.
